Do you have problems with compatibility between different software applications? Does your company have manual processes that could be automated using a standardised interface? Then RESTful APIs (or just REST APIs) can be a solution to your internal challenges. We explain why!

RESTful API simply explained

A RESTful API is like a universal interface through which different software applications can communicate with each other. Imagine you are in an office building and want to get information from another office. The RESTful API is like a standardised door that allows you to get information from that office, regardless of what the internal processes are in that office. You go to the door, knock on it and get the information you need.

Similarly, an application sends a request to the RESTful API, receives a response and can use the data received, regardless of how the backend systems are organised. The RESTful API is therefore a standardised method for exchanging information between different applications, similar to how a door enables access between different rooms.

REST stands for Representational State Transfer and describes a software architecture for distributed systems, especially for web services. Such an interface follows the principle of a client-server architecture in which the client and server are independent components. The client side can obtain information through server requests. The REST architecture follows the principle of statelessness, whereby each request is self-contained and therefore independent of any other. In most cases, the HTTP or HTTPS protocol is used for these requests.

What advantages does REST offer?

REST bietet Unternehmen als Architekturstil für die Entwicklung von Softwareanwendungen eine breite Palette von Vorteilen. REST ermöglicht eine klare und konsistente Strukturierung von APIs, was die Entwicklung, Wartung und Nutzung von Anwendungen erleichtert. Die Nutzung von REST-APIs erleichtert Unternehmen die Skalierung ihrer Anwendungen, da sie keine Informationen über den Zustand der Clients speichern müssen. Diese führt zu einer verbesserten Leistung und Zuverlässigkeit, da die Server entlastet werden und sich besser auf die Verarbeitung von Anfragen konzentrieren können.

Ein weiterer Vorteil von REST liegt in seiner Fähigkeit zur Förderung der Vereinbarkeit und Integration von Systemen. Durch die Verwendung von offenen Standards und Protokollen wie HTTP ermöglicht REST die nahtlose Kommunikation zwischen verschiedenen Anwendungen und Plattformen. Dies erleichtert die Zusammenarbeit zwischen verschiedenen Abteilungen oder externen Partnern und fördert die Entwicklung von umfassenden Lösungen, die verschiedene Softwarekomponenten miteinander verbinden.

Darüber hinaus bietet die ressourcenorientierte Architektur von REST Flexibilität und Freiheit in der Entwicklung und Anwendung von APIs. Unternehmen können APIs genau auf die Bedürfnisse ihrer Kunden und deren individuellen Anwendungen anpassen. Dies ermöglicht es Unternehmen, massgeschneiderte Lösungen anzubieten und sich an die sich ständig ändernden Anforderungen des Marktes anzupassen.

Insgesamt ermöglicht REST Unternehmen eine agile und flexible Entwicklung von Softwarelösungen, die den sich ständig ändernden Anforderungen des Marktes gerecht werden können. Es bietet eine solide Grundlage für die Entwicklung von skalierbaren, leistungsstarken und interoperablen Anwendungen, die Unternehmen dabei unterstützen, effizienter zu arbeiten und wettbewerbsfähig zu bleiben.

Where has soxes used REST?

soxes has used the REST architecture in the development of the instaSOLUTION application, for example. In the communication and management solution, the client communicates with the server via an API to provide all information during operation.

Reichmuth & Co, a renowned private bank, was looking for ways to digitalise its processes. soxes developed a customised consulting tool that combines internal and external processes, reduces the workload for employees and minimises the flood of documents. Intensive collaboration and a UX workshop resulted in a new design concept that takes the bank’s individual requirements into account. The application was integrated into the existing IT infrastructure. In the backend, a REST API was implemented with the ASP.NET framework in the C# programming language. The agile development team at soxes continuously adapts the tool to the needs of Reichmuth & Co. and its customers to ensure a perfectly customised end product.

soxes developed efficient personnel selection software for Assessment Gate based on psychological knowledge, data analysis and artificial intelligence. soxes modernised and expanded the existing HR solution “Prisma World Solution” to automate the assessment process and improve usability. Optimised functions were identified through workshops and integrated into a modern REST interface, supported by WordPress for extended functions. The solution incorporates a complex AI model for suitability determination and provides a fully digitised assessment method. soxes worked closely with Assessment Gate and client representatives to ensure the solution met the requirements.
